Toall whom iii-may concern:

Be it known that I, CHARLEY M. HAIR, a citizen of the United States, residing at Grundy Center, in the county of Grundy and State of Iowa, have invented certain new and useful Improvements in Folding Draw-Bars for Harrows, of which'the following is a specification, reference being had to the accompanying drawings.

This invention relates to folding draw bars for 'harrows and has for its primary object to provide a device of this character which is exceedingly strong and durable in its construction and whereby the harrow sections may be readily disposed in superposed relation When it is desired to draw the harrow through a gate opening or other relatively narrow place.

It is a more particular object of the invention to provide a device for the above purpose wherein intermediate and outer draw bar sections are provided and hingedly connected to each other at their opposed ends, whereby the outer sections can be folded over upon the intermediate section, a front bar rigidly connected to the intermediate section of the draw bar, and hinge rods or pintles removably connected to the ends of the front bar and constituting the hinge pin tles for the draw bar sections.

It is a further general object of the invention to provide a device for the above purpose, which is very simple in its construction highly serviceable and convenient in practical use, and can be manufactured at relatively small cost.

With the above and other objects in view, my invention consists in the novel features of construction, combination, and arrangement of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawing, in which,

Figure 1 is a plan view of a folding draw bar constructed in accordance with the preferred embodiment of my invention;

Fig. 2 is a side elevation showing the harrow draw bar folded; and

Fig. 3 1s a perspective view illustrating the manner of hingedly connecting the outer orend sections of the draw bar to the intermediate section thereof.

Referring in detail to the drawing, 5 designates the intermediate section of the draw bar and 6 the outer or end sections. Each of these draw bar sections is of wood, and

the intermediate section 5 is connected Specification of Letters Patent.

rigidly to a front bar 7 disposed in spaced relation to 'the'bar 5 by means of a plurality of metal straps 8.

To the opposed ends of the draw bar sections 5 and 6, the rectangular metal sleeves 9 are applied and securely riveted, as at 10.

hese sleeves greatly reinforce or strengthen the ends of the draw bar sections and each sleeve is provided with longitudinally projecting knuckles or eyes 11 at the front and rear sides thereof. The knuckles on thes leeve of the outer or end section of the draw bar are adapted to lit between the knuckles on the sleeve secured to the opposed end of the central draw bar section 5. Similar metal sleeves 12 are riveted, as indicated at 13, to the ends of the front bar 7 and are likewise provided with the longitudinallyl projecting knuckles 14. These knuckles 14: are in alinement with the hinge knuckles 11, and hinge rods or pintles 15 are removably engaged through the alined knuckles at the opposite ends of the central draw bar section 5, suitable retaining nuts 16 being threaded upon one end of said pintle rods. The other ends of said rods are provided with the eyes 17 and obliquely disposed rods 18 connect these eyes to the metal straps or loops 19 fixed to the draw bar section 6 adjacent their outer ends. Each of the metal sleeves front side with an eye 20 to receive one end of a rod 21. The rods 21 converge forwardly toward each other and are connected loosely to the bar 22, to opposite ends of which doubletrees 23 are attached.

From the foregoing description, taken in connection with the accompanying drawing, the construction and manner of operation of my invention will be clearly and fully understood. By the provision of the hingedly connected draft bar sections to which harrow sections of any suitable construction are attached, it will be readily seen that the several harrow frames, together with the outer draw bar sections, can be folded over upon the intermediate draw bar 5 and the harrow section connected thereto so that'the entire machine is reduced to the width of one section of the harrow and it can, therefore, be readily drawn through the gate opening or other relatively narrow space. By connecting the outer ends of the draw bar sections 6 to the forward ends of the hinge rods, the harrow may be easily turned. The improved means provided for hingedly con- 12 is also provided upon its necting the draw bar sections to each other is also very durable and permits of the free and easy relative folding movement of the several sections.

While I have herein shown and described the preferred construction and arrangement of the several parts, it is to be understood that the device may be greatly modified in many respects and I, therefore, reserve the privilege of adopting all such legitimate changes as may be fairly embodied Within the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent is:

The herein described draw bar for harrows including intermediate and end seo- Copies of this patent may be obtained for five cents tions, hinge rods connecting said sections for relative folding movement, a front bar disposed in spaced relation to the intermediate draw bar section and rigidly connected thereto, bearings secured to the ends of said front bar, said hinge rods being mounted in said bearings, rigid brace rods connected to the end sections of the draw bar at one of their ends and loosely connected at their other ends to the forward ends of said hinge rods, and draft attachments connected to said front bar.

In testimony whereof I hereunto afiix' my signature in the presence of two witnesses.
